This repository contains the project management documents (in particular GitHub issues) and code that was written as part of our student research project on vision-based page rank estimation with graph networks. Code is four different pieces of software: GraphNets library, RankPredictor, human evaluation tool, and data crawler.

The GraphNets library (/graph_nets/) is our PyTorch implementation of the graph network (GN) framework from Battiglia et al. (2018). It was developed in such a way that other people can use it in their projects too. We use the library in our research to create GNs, train them, and perform inference.

The RankPredictor code (/rank_predictor/) is a collection of Python scripts and classes which are the actual implementation of our method. The code heavily relies on the GraphNets library and implements many of its ab- stract classes. The code contains our models and can be used to reproduce our results.

The human evaluation tool (/human_eval/) is a lightweight Node.js server with a simplistic frontend that was used to determine the human performance on the page rank task. It shows pairs of web pages and asks the user to rank them. The answers are being stored so the human accuracy on pairwise page rank estimation can be output.

The data crawler (/datacrawler/) served the purpose of creating the dataset. It visits web pages, takes screenshots, collects meta information, and stores the collected data. It was developed in C++ with special focus on scalability and modularity.
